Patent GB-1594768-A (GB)
Title: Header
IPC: F28F9/02
Filed: 1978-05-17
Abstract: In a heat exchanger for condensing a gas by passage through vertically spaced heat exchange tubes, flooding of the lower tubes is prevented. A return flow header includes nested baffles which define isolated flow channels connecting one or more predetermined upper heat exchange tubes with a single predetermined lower heat exchange tube. This prevents the condensed liquid in the header from completely filling the lowermost tube or tubes. Removable plugs or plates permit access to the inside of the heat exchange tubes for cleaning.

Title: Improvements in or relating to staple driving machines
IPC: B25C5/11
Filed: 1931-07-14
Abstract: 374,664. Stapling tools. HOTCHKISS CO., E. H., 6, Hoyt Street, Norwalk, Connecticut, U.S.A.-(Assignees of Polyer, F. ; 6, Hoyt Street, Norwalk, Connecticut, U.S.A.) July 14, 1931. No. 20252. Convention date, March 4. [Class 89 (iii).] A stapling tool is adapted to be loaded with a staple strip from the forward end of the tool by the provision, at the forward end of the strip guide bar 16, of a block 39 hinged at its lower end to the base 11 of the tool at 40. The block is held in the closed. position, Fig. 2, by a latch member 41 and can be turned to the position shown in Fig, 5 to allow insertion of the strip 29. The latch is a rotatable plate adapted to engage a notch 43 in the block and held in closed position by a, spring 46. The block houses a pivoted lever 27 which is adapted, under control of a staple already in the driver guideway 26, to prevent a second staple from entering the guideway. The plunger 18 with its driver 25 is held normally in the raised position by a spring 21 which acts between a socket 22 in the plunger and a fixed plate 23. The staple strip is fed by a follower 30 under action of a long spring 31 which, as shown, is led around pulleys 33, 34 through the hollow frame 14, 12, 15 of the tool. The follower can be withdrawn to its rearmost position by a finger piece 36, and retained in this position by a spring-pressed latch 51. The staple guide bar 16 is shrouded at one side by the tool frame and is exposed at its other side. Specification 372,012 is referred to.

Title: Propelling nozzles for jet propulsion gas turbine engines
Inventor: KEEN JOHN MICHAEL STORER
IPC: F02K1/12
Filed: 1959-06-12
Abstract: 875,517. Jet-propulsion nozzles. ROLLSROYCE Ltd. June 3, 1960 [June 12, 1959], No. 20277/59. Class 110 (3). A jet-propulsion nozzle comprising a main variable-area nozzle adapted to be mounted at, or to form part of, the downstream end of the jet pipe and an annular air duct surrounding the main nozzle provided with a secondary variable-area nozzle such that air discharged from the secondary nozzle forms an annular stream closely surrounding the jet gases discharged through the main nozzle, has means for varying the effective areas of the main and secondary nozzles which permits the effective area of the secondary nozzle to be adjusted independently of that of the main nozzle when the latter has a predetermined value. The invention is described with reference to a gas turbine engine having reheat in the jet exhaust pipe. A jet pipe 14 has a main variable-area propelling nozzle 16 formed at its downstream end. The engine and jet pipe are enclosed with a nacelle 38 which defines a by-pass passage 18 supplied with air from the engine compressor. A second variable-area nozzle 20 is provided at the downstream end of the passage 18 and the air flowing through the passage is discharged through the nozzle 20 as an annular stream closely surrounding the jet gases. The outlet end of the nozzle 16 is defined by a series of pivoted flap members 22. Each flap member 22 carries a roller 28 which co-operates with one face of a cam plate 30. The cam plates 30 are disposed in an inclined position and are carried by threaded spindles 32 forming parts of screw jacks 42. The jacks are operated together by an annular ring 44 having internal gear teeth 45. The cam plates 30 are connected together by frusto-conical rings 31. A strut 34 on each cam plate has a roller 35 which engages in a flap 36 mounted on further flap members 37. The flap members 37 are spaced downstream of the member 22 to form a duct 40 communicating with the by-pass passage 18. Each cam plate 30 has a portion 48 which is parallel to the axis of the nozzle 16 so that it is possible to adjust the position of the flaps 37 without moving the flaps 22. This allows the position of the flaps 37 to be finely adjusted to reduce thrust losses. The cam plates may have a flat portion at each end. If desired a flat portion may be formed on each cam plate at a point midway of its length whereby fine adjustment of the flaps 37 under cruise conditions can be obtained.

Title: Manufacture of derivatives of benzanthrones
IPC: C09B49/02
Filed: 1925-08-17
Abstract: A benzanthrone is treated with a sulphur halide, preferably in presence of a suitable solvent and a substance promoting the reaction, in order to obtain benzanthronyl sulphides, and intermediate products which can be converted by alkalies or alkali sulphides into benzanthronyl mercaptans and benzanthronyl sulphides. Benzanthronyl mercaptans can be converted in the usual manner into derivatives such as benzanthronyl disulphide, benzanthronylmethylthioether, or benzanthronylthioglycollic acid. According to an example, benzanthrone is heated in chlorobenzene with sulphur chloride and a little iodine; after removing the solvent the residue is extracted with sodium sulphide or alcoholic alkali, benzanthronyl sulphide remaining; from the solution the sodium salt of benzanthronyl mercaptan is salted out; the sodium salt treated with acids yields the free mercaptan, with dimethyl sulphate the methylether, and with sodium chloroacetate the corresponding thioglycollic acid; the mercaptan yields benzanthronyl disulphide when oxidized.  Specifications 28723/11 and 12614/12 are referred to.

Title: Improvements in aerial arrays

Abstract: 588,044. Aerials. STANDARD TELEPHONES & CABLES, Ltd., and WILLOUGHBY, E. O. Oct. 31, 1944, No. 21297. [Class 40 (v)] A number of dipoles forming a vertical broad band directive aerial array are connected in cascade by a series of transmission line links ; the characteristic impedance of any link is higher than that of the link or line that feeds it, more precisely the link impedance may be equal to the impedance it feeds. Fig. 3 (not shown) illustrates a simple 4-unit array of folded dipoles spaced half of the mean band wavelength apart, the links feeding one dipole from the immediately preceding one having impedances as specified above. In Fig. 4, the dipoles are connected in two series, alternate dipoles being connected by links. The dipoles may be either the simple type shown in Fig. 4 or the cage type of Fig. 2 in which width " w " and depth, " d " can be adjusted to give the best frequency response over the operating range ; in either case when the switches 5 are open, the dipoles are of the full-wave type and when they are shut the dipoles become half-wave operating, on a band of frequencies half those in the full- Wave case. The coverage of the array is thus increased by the choice of two frequency bands. In Fig. 4, the feeder links should be one Wavelength long at the mid-point of the lower frequency band and the separation of adjacent dipoles a quarter wavelength, link 13 may be two, and link 14 one, wavelength long. The links in this example are longer than the direct spacings and, if desired, they may be shortened by using series loading coils with the appropriate shunt capacitors, Fig. 5 (not shown). The arrays may be provided with reflectors consisting of a similar series of dipoles mounted a quarter wavelength behind the first series ; arrays with reflectors, however, only work for one frequency range, i.e. with switches 5 permanently open or permanently shut ; and the reflector spacing is arranged correctly for the mid-point of the range. The reflector dipoles may be unfed and terminated by their equivalent impedance, or connected by a separate series of links exactly similar to the first, but fed in phase quadrature, or each dipole of the reflector may be energized from the terminals of its associate main array dipole by means of a quarter wavelength link. To take into account the mutual inductance between the array and reflector dipoles, small adjustments in dipole length may be required. Fig. 7 (not shown) illustrates an experimental method of determining the adjustment for the last. type of reflector connection described above. The Provisional Specification states that in an array without reflectors and with switches 5 closed, the dipoles will operate in half and full wave modes simultaneously if desired.
